EcoWorld has refined the use of plastic bottles as a construction material. By filling the bottles with soil and surrounding them with cement, homes built using plastics bottles are strong, weather resistant and long lasting.

The time required to fill each bottle with soil makes plastic bottle construction not as time efficient as using traditional building methods. However, in rural areas, where other building material may be scarce or expensive, families can work in their own time to build walls or homes using this construction technique.
